How to know if lines are proportional

normally they'll be the same length, or you can multiply one line by a number to get the other line

A line is proportional if the y-intercept is at 0,0. So your equation might look like y=4x. But it can't be y=4x+1. Since then the y intercept is at 0,1.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
